ClearCard allows you to keep your apps open and your wallpaper visible. By appearing almost entirely invisible when minimized, ClearCard can sit front and center on your Pre or Pixi, without blocking the view of your wallpaper. ClearCard also includes a time/date widget that can be turned on or off.
When your wallpaper changes, ClearCard automatically adjusts to continue appearing nearly invisible.
When you maximize ClearCard, it shows your entire wallpaper, completely clean as if you had minimized all your cards.
ClearCard does not make your other applications clear, but is itself clear, allowing you to keep your wallpaper visible when ClearCard is in the center.
